WATER-CLOSET.

Specification of Letters Patent.

Patented Feb. 18, 1919.

Application filed January 15, 1914. Serial No. 812,193.

To all whom it may concern:

Be it known that 1, JOHN J. DALY, a citizen of the United States, and a resident of the city of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Water-Closets, of whlch the following is a specification, reference being had to the accompanying drawings.

The main object of this invention is to provide in a water closet a stool of improved construction in combination with a floor pipe or discharge pipe of improved construction, whereby all leakage of gas between the stool and floor pipe is prevented by a liquid seal which is renewed at each operation or flushing of the stool.

A further object of this invention is to provide an improved connection between the stool and the floor pipe, whereby the pipe is rotatively adjustable with respect to the stool and may be secured to the stool at any point in the rotation of the pipe.

Further objects of this invention will appear hereinafter.

In the accompanying drawings, Figure 1, is a vertical central section of a closet constructed in accordance with this invention; Fig. 2, a fragmentary top plan view of the same; Fig. 3, a horizontal section of the same on line 33 of Fig. 1; Fig. 4, a bottom plan view of the stool; Fig. 5, a top plan view of the discharge pipe; Fig. 6, a fragmentary vertical section of a modified form of this invention; and, Fig. 7 a fragmentary top plan view of the parts shown in Fig. 6.

Referring to the drawings, one embodiment of this invention shown therein comprises a stool 10 made of porcelain or other suitable material and provided with a base 11 preferably integral therewith adapted to rest upon a floor 12, and to be secured thereto in any suitable manner. The stool 10 comprises a bowl 15 which is surrounded along its upper margin by an internal annular conduit 16 provided with a Series of outlets 17 for discharging water into the upper portion of the bowl. The conduit 16 communicates with an inlet compartment 18 arranged in the rear upper portion of the stool and having an inlet 19 which communicates through a supply pipe 20 with the usual tank (not shown) or other means for supplying water at intervals to the compartment 18 for flushing the closet. The inlet compartment 18 is provided with a substantially horizontal bottom wall 25 and serves as an immediate reservoir or source of water supply for the closet.

The lower portion of the bowl 15 is provided with an inclined inlet 26 supplied with water by a pipe 27 inclined upwardly from a point beneath the inlet 26 and communicating at its upper end with the inlet compartment 18 through a suitable aperture in the partition 25.

The stool 10 comprises suitable internal walls 30 forming in combination with the walls of the bowl 15 a siphon discharge duct 31 having at its upper end an inlet 32 communicating with the lower portion of the bowl 15, and at its lower end an outlet 34 formed by a tubular projection 35 depended downwardly from and preferably integral with, the base 11 of the stool, and extending through the floor 12. The tubular projection 35 is provided with a preferably integral tubular extension 36 depending downwardly therefrom, and of substantially the same external diameter as, but of greater internal diameter than, the tubular projection 35. The tubular projection 35 is preferably provided at its lower end with a downwardly depending internal marginal integral lip 37 forming with the internal surfaces of the projection 35 and the extension 36 an internal downwardly facing annular recess 38 in the lower end of the projection 35.

Depending downwardly below the stool 10 is a discharge pipe 40 communicating with the outlet 34 of the discharge duct, and having a preferably substantially uniform internal diameter slightly greater than the diameter of the outlet 34. The discharge pipe 40 is provided with an upper substantially vertical cylindrical inner tubular portion 41 surrounded by, coaxial with, and spaced from the tubular extension 36 and having its upper edge 42 engaging in and spaced from the walls of the annular recess 38 and in a horizontal plane slightly below the horizontal plane of the lower edge of the lip 37. The discharge pipe 40 is also provided with an outer tubular substantially cylindrical wall 43 surrounding and coaxial with the upper portion of the discharge pipe, and surrounding and spaced from the tubular projection 35 and its extension 36. This outer wall 43 is connected to the body of the discharge pipe 40 as at 44 in a substantially horizontal plane slightly below the lower edge of the tubular extension 36, and is provided at its upper edge with an outwardly extending flat annular flange l5 which engages against the under surface of the base 11 of the stool 10 in an annular recess 46 provided therefor in the under side of the base. The discharge pipe i0 thus forms in combination with the tubular projection 35 and tubular extension 36 of the stool 10 a trap-saaped passage at.

For clamping the discharge pipe l0 securely in any desired position of rotary uCl justment with respect to the stool 10, an annular clamping plate 50 is or anged loosely within the annular recess and is provided with an internal flange 51 which engages against the under surface of the flange d5 of the discharge pipe. This clamping plate 50 is arranged to be drawn upwardly to clamp the flange a5 of the discharge pipe l0 against the corresponding flat under surface of the base 11 by means of two or more bolts extending loosely through apertures provided therefor in the base 11, and threaded at their lower ends into the annular clamping plate 50, each bolt 52 being provided at its upper end with a head 53 of hexagonal or other suitable shape.

An annular gas ret 55 of rubber or other suitable material may be arranged between the base 11 and the flange 4E5 in suitable cooperating annular recesses 56 and 57 provided therefor in the under surface of the base 11 and the internal marginal portion of the flange 2P5 to prevent leakage between the stool 10 and the discharge pipe 40. This gasket 55 surrounds and is in contact with the outer cylinddcal surface of the tubular projection 35 and forms a closure for the upper end of that portion of the trap-shaped space 47 which lies between the outer sur face of the tubular projection and the inner surface of the outer tubular wall 4-3, the gasket being normally held in a compressed state by the clamping action of the flange e5. Prior to this invention it has been customary to inserta rubber gasket between the stool and the discharge pipe to prevent leakage of gas or water, but it has been found in practice that such a gasket is apt to gradually deteriorate and to eventually be insuiiicicnt to prevent this leakage. The present invention uses this gasket only as an auXilli-ary means and provides a liquid seal between the stool and the discharge pipe as will appear hereinafter, and thus provides means which will prevent any leakage during an indefinite period of use. Thus the rubber gasket 55 being only an additional means for preventing leakage might be omitted without rendering the device subject to leakage under ordinary conditions of use.

For injecting water into the trap-shaped space 47 between the stool 10 and the discharge pipe to as a result of the admission of water intothe inlet compartment 18 of the stool, a plurality of apertures converge upwardly and inwardly from that portion of the trap-shaped space 47 which lies between the tubular projection 35 and the outer tubular wall i3 and communicate at their upper ends with an annular passage 66 which surrounds the lower portion of the siphon discharge duct 31 being formed by a partition 67 integral with the stool l0 and extending from the upper surface of the base 11 to the wall 30 of the siphon duct 31. This annular passage 66 conununica'tes with the lower portion of a space or passage 68 between the wall 30 of the siphon duct 31, the rear wall 69 of the stool, and which passage extends upwardly and communicates at its upper end, through a plu- "ality of apertures 7.0 through the partition 25, with the inlet compartment 18, and also communicates at its upper end through a branch passage 71 with the upper portion of the interior of the bowl 15, this branch pas sage se'ving as an air vent for the air displaced by the water in falling through the passage 68. The converging apertures 65 are preferably spaced uniformly and arranged in radial planes around the vertical axis of the tubular projection 35, the sum of the cross-sectional areas of these apertures being preferably slightly greater than the sum of the cross-sectional areas of the apertures through the partition 25, so as to provide a free passage of the water into and through the trap-shaped space 47 to prevent an excessive accumulation or backing up of the water in the passages 66 and 68'of the stool 10.

An. aperture 75 is arranged through the rear wall 69 of the bowl and in horizontal and axial alinement with the annular passage 66 surrounding the lower portion ofthe siphon duct 31 to permit of the convenient cleaning of this annular passage and the passage 68 leading upwardly therefrom. This aperture 75 is normally closed bv anv suitable removable plug 76. I i

The construction of this closet is such that when the usual predetermineo amount of water is allowed to flow into the inlet compartment 18 of the closet through the supply pipe 20 by the manual operation of a valve (not shown) in a well-known mannor, a portion of this water will flow around the annular conduit 16 and through the openings 17 into the upper part of the bowl 15, while another portion of the water will flow downwardly through the pipe 27 and pass upwardly through the opening 26 in the form of a siphon et. and a third portion will pass downwardly through the openings 70 into the passage 68 and then through the annular passage 66 and aperture 65 into the trap-shaped space 47 between the stool 10 and the discharge pipe 40. The water passages between the inlet compartment 18 and the trap-shaped space t? are so designed as hereinbefore described, that the water will not rise in the trap-shaped passage 4? much above the lower ends of the apertures 65 and will at no time reach the level of the gasket 55 but will pass downwardly from the lower ends of the apertures 65 and around the lower end of the tubular extension 36 thence upwardly between the tubular extension 36 and the inner tubular portion ll of the discharge pipe 40, inwardly over the upper end of the tubular portion 41 and downwardly through the space between the upper edge of the tubular portion 41 and the lower edge of the lip 37 into the upper end of the discharge pipe 40. This passage of the water from the trap-shaped space l? into the discharge pipe 40 is facilitated by the action of the water simultaneously passing downwardly through the outlet 3% of the siphon duct 31 which tends to create a partial vacuum in the trap-shaped passage 47 in a manner analogous to the action of the well-known Sprengel air pump. After the inlet compartment 18 has been entirely emptied of water and that portion of the water which has passed through the aperture 70 has all passed downwardly through the apertures 65 and into or through the trapshaped space 47, a portion of this water will remain therein to form a liquid seal between the stool 10 and the discharge pipe 40, this water forming the seal being renewed or replaced by fresh water each time that the closet is operated or flushed as hereinbefore described. This liquid seal between the stool 10 and the discharge pipe d0 acts to positively and absolutely prevent any escape of gases, either noxious or otherwise, into the atmosphere through the joint formed between the stool 10 and the discharge pipe 40, while the renewal of the water seal at the trap at each flushing or operation of the closet prevents the seal from becoming contaminated and, therefore, is advantageous; but it is evident that in the construction of this closet the passages 65, 66, 68, and provided for the renewal of the seal, might be omitted and a permanent liquid seal of water or mercury or any other suitable liquid might be arranged 1n the trap-shaped passage 47 to perform the function of preventing the escape of gases through the joint between the stool 10 and the discharge pipe 40.

Instead of clamping the discharge pipe 40 to the stool 10 by means of an annular clamping plate 50 and bolts 52, the annular clamping plate 50 may be omitted and the flange 45 of the discharge pipe to provided with a large number of threaded apertures 80 and the discharge pipe 40 may then be clamped in any desired posit-ion of rotary adjustment by means of two diametrically opposed bolts 81 extending downwardly through slightly elongated arcuate recesses 82 provided therefor through the base 11, as shown in Figs. 6 and 7 and at points corresponding to the location of the bolts 52, shown in Figs. 1 and 3, only one of the bolts 81 being shown in Figs. 6 and 7.

It will be evident that this change in the construction as well as various other changes may be made in applying the invention, and that the invention may be readily adapted either to various forms of closets such as are now in general use or to any suitable form which may be devised. It will also be evident that instead of leading the water through the stool and into the trap through the form of passage shown, it may be carried into the trap through any other suitable passage either through the stool or otherwise. Furthermore, although only two embodiments of the invention have been herein illustrated and described it is not thereby intended or desired to limit the invention to any specific construction as it may be readily applied in various other forms without departing from the spirit or scope of the invention as defined in the appended claims.

Having thus fully described this invention I claim and desire to protect by Letters Patent of the United States:
